Whenever the occursCount function should return the value of one, this error is seen instead:

[error] Test edu.illinois.ncsa.daffodil.section23.dfdl_expressions.TestDFDLExpressions.test_occursCount_1b failed: java.lang.Exception: Runtime Schema Definition Error: dfdl:occursCount did not receive a NodeSeq back, check your path.

The exact same schema works when occursCount is greater than 1.

See tests:
occursCount_1b
occursCount_3b
